Cases of spinal cord injuries sustained by construction workers during the raising of preconstructed wood framed walls for single family houses were described and the implications of such injuries were examined. A spinal cord injury sustained by a construction worker during the raising of a preconstructed wall was investigated following a report to the Colorado Department of Public Health and Environment Sentinel Event Notification System for Occupational Risk. The worker was injured when the wall, which was too heavy for the three workers trying to install it, fell on him resulting in a dislocation of the seventh thoracic vertebra and spinal cord injury. The investigation of this incident revealed that this building technique was common and another similar accident resulting in a disabling spinal cord injury was identified in California. Regulations promulgated by the California Occupational Safety and Health Standards Board with regard to the raising of wood framed walls at construction sites designed to decrease the incidence of injuries were described.
